TUBE FRAME FOR AXMINSTEB, LOOMS.

Application filed November 19, 1923.

To all whom it may concern.

Be it known that we, GEORGE D. Locuwoon and WALTER H. lVAKnFmnn, citizens of the United States, both residing at lVorcester, in the county of Vorcester and State of Massachusetts, have invented a new and useful Tube Frame for Axminster Looms, of which the following is a specification.

This invention relates to tube frames for .Axminster looms and more particularly to the construction of the brackets by which. the tube frames are connected to the chains ordinarily found in this type of loom.

An object of the invention is to provide a tube frame having a spool bearing formed. with an integral tongue which secured directly to a portion of the bar comprising the yarn tube supporting portion of the tube frame, the spool bearing being embraced by a pair of cars formed with the bar and serving to prevent movement of the spool bearing longitudinally of the tube frame.

A further object of the invention is to provide a bracket with a chain engaging portion which shall be readily removable from the tube frame only in a direction sub stantially at right angles to the line of strain to which the bracket is subjected when supporting the tube frame in the chain.

A. further object of the invention is to provide a tube frame with spool bearing and chain engaging portions each of which shall have interengaging members by means of which each part will brace the other against relative lateral motion, the parts being held together by removable means.

With these and other objects in view which will appear as the description pro reeds, our invention resides in the arrangement and combination of parts hereinafter described and set forth in the claims.

In the accompanying drawings- Fig. 1 is a side elevation of one end of a. tube frame embracing our invention,

Fig. 2 is an end view ofthe structure shown in Fig. 1 with the spool omitted,

Fig. end of the spool bearing member,

Fig. 4 is a view similar to Fig. 3 but showing the lower end of the chain engag ing member, and

3 is a perspective view of the lower Serial NO. 875,470.

Fig. 5 is a. perspective view of one end of the tube frame before the bracket is applied thereto.

Referring more particularly to the draw jugs, it will be seen that the tube frame is formed of a hollow tubular bar 10 to which aresecured the yarn tubes 11 held thereto by means of angle strip 12 in any approved manner. A. spool 13 of the usual construe tion has a gudgeon 14- which is received. in the spool bearing 15.

One feature of our invention concerns the spool bearing member 16, the lower end of which is formed indicated in Fig. it with the tongue 17 projecting somewhat below the shoulders 18 formed onthe'bottom of the spool bearing member. The lower portion of the tube frame 10 is provided with a slot 19 into which the tongue 17 extends and in which said tongue is riveted. E tending from the vertical walls of the tube frame 10 are ears 20 which are bent inwardly toward each other and lie beyond the vertical plane of the slot 19. The ears 20 pass around the outer face of the spool bearing inembe 1.6 and together with the tongue 17 serves to hold said member rigidly to the bar 10.

The bottom and lower portions of the side walls of the tubular bar are extended as indicated at 21 to g'vc lateral support to the lower end of the chain engaging member 22 and also to afford a smooth bottom for the tube frame and to protect the member 22. The latter member is reduced as at 2 to accommodate the ears 20 and has a relatively thicker portion defining a rib the upper edge of which lies under and engages the ears 20 as indicated in Fig. 1.

The chain engaging member 22 is provided with a slot 25 through which extends the usual chain engaging spring member 26. The slot 25 extends downwardly somewhat along the vertical inner portion of the chain. engaging member 22 and in order to give lateral support to the latter member we strike up a tongue 27 from the member 16 so proportioned and positioned as to lie in the bottom of the slot 25, thereby preventing side motion of thebracket forming members with respect to each other. Screws 28, located between rib 52 i and tongue 27, are provided to extend through the chain engaging member into tllv spool bearing memher to provide detachable means by which member may be removed from the tube frame.

It will be seen from an inspection of Fig. that the bottom of the tube frame extends beyond the slot 19 as at 29 and when it is desired to remove the spool bearing member he tube frame may be inver r and supported on any convenient ledg (not shown) to support the tubular memb while the tongue is being forced out of the slot 1 From the foregoing it will be apparent that we have provided tube frame wherein the spool bearing men-ab r is riveted di rectly to the tubular bar and held thereto by embracing ears; that the chain engaging men her is not only readily IQITLO FEI DlQ from the tube frame but is held against transverse motion with respect to the tube-- lar bar and the spool bearing member 10 by means of the extended side portions 21 and the tongue 27, and that the rib 21- of the chain engaging member is positioned to engage the lower edge of the ears 20.

o have shown herein a construction wherein the chain engaging member is reducecd in thickness at the lower end thereof but we do not wish to be limited to this construction, as it is possible to form this member of material of uniform thickness throughout its length.

Having thus described our invention it rill be evident that changes and modifications may be made therein by those skilled in the art and we do not wish to be limited to the details herein disclosed but what we do claim is:

1. In a tube frame for nxminster looms, a hollow tubular bar, a spool supporting bracket member having the lower end formed with a tongue integral therewith and xtending into an opening in the bar and expanded in said opening, to prevent vertical transverse movement of the member with respect to the bar, means integral with the bar to limit longitudinal and horizontal transverse movement of the bracket member relative to the hollow bar and a chain engaging member carried by the spool bearing member.

2. In a tube frame for Axminster looms, a hollow tubular bar, a spool bearing memher having an integral tongue extending therefrom into an opening, in one wall of the bar and expanded into said opening to lOlCl said member to the bar, ears formed integral with the hollow tubular bar and surrounding a portion of the spool bearing member, and a chain engaging member held to the spool bearing member and having a portion lying-under said ears.

3. In a tube frame for Axminster looms, a hollow tubular b r, a spool bearing member having an integral tongue extending into an opening in one wall of the bar and expanded in said opening to hold said mem her to said bar, said wall being extended beyond the said member, to form means adjacent the member by which said bar may be supported when removing the riveted portion of the member, and a chain eng I ing member having a portion guarded my said extension of the said wall and secured to said first named member.

l. In a tube frame for Axminster looms. a yarn tune supporting bar, a spool bearing member secured to the bar, means on said he projecting beyond the spool bearing member and presenting a lifting edge, a detachable chain engaging member attached to said first named member, and a rib formed on said chain engaging member and lying under the lifting edge, and a chain hook member carried by said chain engaging member.

.5. In a tube frame for Axrninster looms, a hollow tubular bar, a spool bearing mem ber, means to secure the member to the bar including ears integral with the bar and extending around a portion of said member, a chain engaging member, detachable means to secure the second member to the first, a rib on said chain engaging member lying under said ears, and a chain hook secured to the chain engaging member, said rib supporting the bar independently of the detachable means.

6. In a tube frame for Axminster looms, a hollow tubular member, a spool bear g yan tube supporting bar, secured thereto, a detachable clain engaging member attached to the spool bearing member, and means rigid with and projecting from one of said members and extending into a Slut formed in the other member to prevent relative transverse movement of said 111C213- bers.

7. In a tube frame for Axminster loom a yarn tube supporting bar, a spool bearing member secured to said bar, a chain ongav ing member, means for detachably securing the chain engaging member to the spool. bearing member, and means extending from the first named member across the plane of the other member to engage said other member and prevent relative transverse movement of said members independently of said detachable securing means.

In testimony whereof we have hereunto atlixed our signatures.
